Replacing Touchscreen Controllers on EZ MAXX™ and MAXX Elite™

Games

If you are replacing the touchscreen controller on an EZ MAXX™ or MAXX Elite™
game with an SMT4 controller, you will need to disconnect the ground connector on the
touchscreen overlay.  The controller will short out if the ground is not disconnected and
the game is turned on.

Make sure the game is turned off and disconnected from its power source.  After
replacing the touchscreen controller, locate the touchscreen overlay ground connector
(see Figure 1) and disconnect it.  It is recommended that you completely cover the
connector itself with electrical tape, as it can NOT come into contact with any metal
inside the game.
